System and method to detect child presence using active mems sensors

摘要: The presence of a child within an enclosed space in appliance, such as washing machine, dishwasher or refrigerator, is detected using one more MEMS sensors positioned to detect movement the through various measured characteristics. In preference, combinations different types are utilized movement. Movement may be attributed inside space, rather than resulting from other influences, with increased reliability if determination made based upon Safety processes initiated detecting child.
